I have created a virtual machine for Ubuntu with Microsoft Virtual PC. When i start it i can choose either CD or ISO to install Ubuntu. However, it doesn't start. It asks me to put cd or show the iso file again. What can be wrong?

Works fine for me on VPC 2007 SP1

Make the VM, and at the top click CD then Capture ISO Image.

Point it at the saved .iso file. Click open. It should then boot off the cd no problem.

When i hit F4 it shows the manu otherwise blank screen.
Solved thanks

When it generates an error something like "You haven't shown the file or the cd...." press F4. Then it show the installation sceen.
